I have a 2001 Lexus LX470 that won’t charge the battery. The alternator, the belt tensioner and the serpentine belt were replaced today. It still won’t charge and I am lost at what to look at next. The two frame grounds near the battery have been checked, cleaned and tightened. All of the fuses are good. The junction/assembly box off of the positive battery cable was disassembled and the connections cleaned. (I may try replacing this so if anyone knows a way to either better wire it or a part number that would be appreciated.) But all connections and grounds everywhere seem to be in good shape. When the voltmeter is on the hot post of the alternator and grounded, it still reads low. I’m lost and don’t know where to look next. Thanks I’m advance.
